In the figure two curved plastic rods, one of charge +q and the other of charge -q, form a circle of radius R = 4.00 cm in an xy plane. The x axis passes through both of the connecting points, and the charge is distributed uniformly on both rods. If q = 15.2 pC, what is the magnitude of the electric field produced at P, the center of the circle? Number i Units +9 -9 N/C or V/m
